WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 754,733, dated March 15, 1904.

Application filed July 9, 1903. Serial No. 164,764. (No model.) I

To aZZ whom it may concern.-

Be it known that I, PATRICK A. ALLEN, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio,have invented certain new and useful improvements in W ater-Closets; and I do hereby declare the following to be afull, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figiires of reference marked thereon, which form a part of this specification.

My invention relates to automatic dumping and flushing mechanism for water-closets, and has particular reference to improvements on the mechanism described and claimed in United States Letters Patent No. 717,651, granted to me January 6, 1903. I

The object of my invention is to reduce to a minimum the quantity of water used in the flushing of water-closets and to cause an automatic flushing of the hopper and dumping of the excretions therein as the seat rises to a perpendicular position after it has been released, thus providing a water-closet particularly adapted for use on railwaycars and in other places where the facilities for carrying water or retaining excrement are limited.

While the essential features of my invention are necessarily susceptible of modification, the preferred embodiment thereof is illustrated in the accompanying drawings, in which Figure 1 is a partly-vertical sectional side elevation of my. improved closet, showing the position of the several parts when the seat is in closed position. Fig. 2 is a similar View showing the positions'of the parts when the seat is in open vertical position. Fig. 3 is a view similar to Fig. 1, showing the positions of the parts when the seat has raised sufiiciently to cause the dog to be released to allow the flushing and dumping mechanisms to return to their normal positions; and Fig. 4:18 a plan view of Fig. 2, showing the seat removed.

In the drawings, 1 represents the hopper or bowl of my closet, which is provided with a flange 2 to adapt it to be supported by the enlarged chute or housing 3 and has its lower or contracted portion extended a short distance within said chute. The seat 4 has its supporting-bracket 4E rigidly secured to the shaft 5, journaled to the lugs 6 6 of the hopper and is adapted to be automatically raised and normally retained in vertical or open position by means of the coiled spring 7, mounted on said shaft and bearing against the bracket 1 of the seat and the web 6, interposed between the lugs 6 6.

'A disk 8, having its periphery laterally flanged, as shown, is loosely mounted on one end of the shaft 5 and incloses the sleeve 9, which is made rigid to said shaft and provided with a boss to form afulcrum for the dog 10. The dog 10 when .the seat is down is adapted to engage with a rack or tooth 11,securedto or formed integral with the inner periphery of the flange of the disk Sand is adapted to beheld in engagement therewith by means of the spring 12. The free end of said spring is provided with a shoe 13 to adapt itto have a sliding engagement with the inner periphery of said flange and cause said disk to have a retarded movement when moving independent of and in the opposite direction to said shaft 5. Other suitable retarding means may be used, however, for this purpose.

A trip-chain 14, which leads to and operates a flushing-tank, (not shown,) passes under the pulley 1 1, secured to the wall or other stationary object and has its end attached to the periphery of said disk 8, thus causing the same to be pulled and the hopper to be flushed when the disk 8 is rotated by the raising of the seat 4:. V

A concave or cup-like trap 15 is rigidly secured to the shaft 16, mounted within the enlarged chute 3 in adjacent position to the throat of the hopper 1 and is adapted to fit loosely around the projecting end of said hopper and form an air-tight seal for the same when said trap is closed and filled with water. The trap 15 is normally retained in closed position, as shown in Figs. 1 and 2, by means of a coiled contraction-spring 17, which engages at one end with an arm 16 on one end of the shaft 16 and at its other end with the floor or other stationary object. An arm 16 is secured to the other projecting end of the I shaft 16 and is connected tothe disk 8 by means of the rod 18, which is pivotally attached to the boss 18, projecting from the periphery of said disk.

19 is an arm adjustably secured to the rod 18 and adapted ata predetermined point in the ascending movementof said rod to engage with a stud 10, mounted on the dog 10, and cause said dog to be released from the rack 11, thus enabling the disk to return to its normal position and causing the flushing to cease and the trap 15 to close.

I have found in the operation of my invention that more satisfactory results are obtained by causing the seat 4 to have a retarded ascending movement after it has been released, as otherwise the spring 7 causes a too rapid movement of the seat and consequent stopping of the flush before it has thoroughly performed its work. I have therefore provided an oil or air cushion 20 of the ordinary type, one end of which is connected to a stationary object and the other to a crankarm secured to or formed on the free end of the shaft 5.

It will be apparent that my invention Will normally remain in the position shown in Fig. 2, the trap 15-being closed to form a water seal and the seat in elevated position. When it is desired to use the closet for other than urinal purposes, the seat is drawn down, thereby causing the shaft 5 and sleeve 9 to be turned to the left within the disk 8 and the dog 10 to engage with the rack or tooth 11, as shown in Fig. 1. The seat A on being released has a retarded ascending movement, and the disk 8 is slowly turned, by reason of the dog 10 engaging therewith, until the ascending movement of the rod 18 has been sufficient to cause the arm 19 to engage the stud 10, as shown in Fig. 3, and release the dog 10 from the rack 11, permitting the disk 8 and connected parts to return to their normal positions, the return movement of said disk being retarded by means of the springpressed shoe 13, engaging with the flange of said disk. It will be understood that the rotation of the disk 8 as the seat is raised causes a simultaneous opening of the trap 15 and flushing of the hopper of the closet, the said flushing operation continuing until the disk has returned to its normal position on the release of the dog 10, the said trap closing in time to catch a supply of water to form a seal.

It will be understood from the above description that the flushing of my closet will require a very small quantity of water, which may be regulated by the adjustment of the arm 19 on the rod 18, thus making it possible to equip cars and other places having limited water-supplies with sanitary water-closets.

It is obvious that such changes in the form, proportion, and minor details of construction of the parts as fairly fall within the scope of my invention may be made without departing from the spirit or sacrificing any of the advantages thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
